gianfar: Enable changing mac addr when if up
Use device flag IFF_LIVE_ADDR_CHANGE to signal that the device supports changing the hardware address when the device is running. This allows eth_mac_addr() to change the mac address also when the network device's interface is open. This capability is required by certain applications, like bonding mode 6 (Adaptive Load Balancing). Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.com> Signed-off-by: David S.
